2 Days Frequency

Why the 2 Day frequency doesn't work?On a daily symbol I selected "other" frequency and add a 2 days frequency, but chart keeps on 1 day data.Also I added a new time-based bar frequency of 2 days, and run a system, but the system run on one day data.I had no problems in minutes frequencies. The problem is just for frequencies from 2 to 4 days.Thanks in advance
